craving. These correlations decreased in magnitude from 0 to 5 hours after participant’s last cigarette (B = 0.066, t = 9.54, p < 0.001) and then proceeded to increase thereafter (B = −0.24, t = 12.69, p = 0.05, correlation magnitudes shown in Figure 3). Subject-level withdrawal/NA and PA slopes were significantly and negatively correlated at all time points (r-range: −0.444, −0.800, p’s < 0.05, Figure 3) suggesting that those participants who experienced greater increases in withdrawal/NA also experienced greater decreases in PA. This correlation was found to increase in magnitude over time (B = −0.087, t =−6.38, p < 0.001). In sum, participants’ rates of change in withdrawal/NA and craving were only observed to be correlated late in the day whereas participants’ rates of change in positive affect were negatively correlated with rates of change in craving and withdrawal/NA throughout the day.
